webView:didFinishLoadForFrame: and incomplete DOM



Hi all,

I've got an application that uses WebKit to display web pages that I generate on the fly. My app takes a single HTML file (built into the Resources folder), then uses XSLT stylesheets to break it into up to five different frames. Note that the frames always have the same path each time they are generated. The main frame is then handed to WebKit via loadRequest:.

As the frames load, I catch the notifications with webView:didFinishLoadForFrame:, then walk the DOM (via DOMDocument on the frame) looking for certain tags. Most of the time this works without problem. However, sometimes one of the frames does not have a complete DOM; it only has the HEAD, not the BODY. Therefore I don't find the tags I'm looking for.

That said, all the frames always render correctly, even the nodes that did not show up in the DOM. When I go look at the HTML of the frame that did not load, it is correct, and in fact identical to the HTML that did load on a previous try.

Although I cannot prove it, it appears that webView:didFinishLoadForFrame: is firing prematurely in some cases. Has anyone else seen this, and, more importantly, know of a fix or work around for it?

Thanks,

	-andy
